Analog Devices Inc. MAX15157 60V Current Mode Buck Controllers
Analog Devices Inc. MAX15157 60V Current Mode Buck Controllers drive two external MOSFETs in a half-bridge buck configuration. The output voltage can be dynamically set through the 1V to 2.2V reference input (REFIN) for modular design support. The switching frequency is controlled by an external resistor that sets the internal oscillator frequency. MAX15157 can also be controlled by synchronizing the regulator to an external clock. The device is designed to support 120kHz to 1MHz switching frequencies.
